  1. AUC area under the curve, eFRS epigenetic frailty risk score, F-BL baseline frailty status, F-2Y 2-year follow-up frailty status, F-5Y 5-year follow-up frailty status, F-8Y 8-year follow-up frailty status, F-11Y 11-year follow-up frailty status.
  2. aP-value for adding eFRS to the model containing age and sex (two-sided P-value with adjustments).
